Word scramble
Unscramble the letters and write each key term on the line.
1
SETT ATAD
Chosen inputs, each with the output you expect, picked so every path (branch) through an algorithm gets tested. Compare the real result to the expected output.
2
YROOSDBATR
A row of numbered screen sketches with arrows showing the order a user moves through them, so you can plan how someone gets from the first screen to the last.
3
IARICTRE BEATL
A table that lists each design option against the same criteria, rates each one, and helps you pick the best design and give reasons for your choice.
4
APGRRMO
A text file of Python instructions. You write it in the editor, and when you press Run, Python does each line in order from first to last and shows the output in the output panel.
5
TUN(IITPN())
input() gives text, so int() wraps it to turn the typed text into a whole number you can calculate with. Use float() for decimals. str() turns a number back into text.
6
DAN, RO, TNO
Logical operators that combine or flip True/False conditions. and needs both True, or needs at least one True, and not reverses True to False (or False to True).
7
FI SDEINI A OOPL
An if indented inside a loop's block is checked again on every repetition, so each pass can make a different decision.
8
ERBKA
A keyword that stops the loop it is in straight away. The program then carries on with the first line after the loop. It is often used inside while True to exit when a condition is met.
9
DUPS.NLEALA(IEVPT)
Adds a value to the end of a list, making it one item longer. Start with an empty list like scores = [] and use append() in a loop to build it up.
10
EFD ANME():
Creates a function: a named, reusable block of indented code that only runs when you call it. Define it first, then call it.
11
OLLCA IRAABEVL
A variable created inside a function. It only exists in that function, so using it outside gives a NameError. A variable made outside all functions is global and can be used anywhere.
12
FI / EILHW
A flowchart diamond (a decision) becomes if, or while when an arrow loops back to it. Rectangles become statements and parallelograms become input() or print().
13
FIYDOM EOCD
Read a working program, then change one part, like a value, condition or message, to get new behaviour. Predict the result first, change one thing at a time, then run it.
14
UURFET CPIATM
An effect a solution could have later on people, the environment or the economy, such as energy use, jobs or privacy.

1SETT ATAD → test data — Chosen inputs, each with the output you expect, picked so every path (branch) through an algorithm gets tested. Compare the real result to the expected output.
